Nat Brown has returned to the Club on loan from Macclesfield Town.
Brown, who made 107 League and cup appearances for the Imps between 2005 and 2008, goes straight into the squad for this afternoon's Blue Square Bet Premier game against Woking.
Handed the number 25 squad shirt, Brown's loan will run until the end of the season although a clause in the deal means he won't be able to face his parent club at Moss Rose in Wednesday night's fixture between the two clubs.
Brown initially joined the Imps from Huddersfield Town in the summer of 2005, having worked his way through the youth system at the Yorkshire side. He played in a number of positions, before settling in a central defensive role, and went on to make over 80 appearances for the Terriers, including over 50 starts in the Football League.
He was a regular in the City side until a wrist injury sustained towards the end of the 2005/06 season and required surgery during the summer break, forced him to miss the first 13 matches of the following campaign.
His final Football League outing in an Imps' shirt came at Peterborough United in March 2008 and following his departure from Sincil Bank he had a brief spell at Wrexham before linking up with Keith Alexander and Gary Simpson at Macclesfield.
